Ensuring BAL genuinely is zero or so low as to be at the limits of detection is necessary for research purposes in order to distinguish between hangover and acute alcohol intoxication.

Therefore, while some papers were identified school trip essay in english database searches, the majority were identified from references cited in papers already obtained.

Typically, in a between-subjects design, alcohol is given to one group and placebo is given to another group. Decrements in the alcohol group relative to the placebo group are interpreted as hangover effects.

Key aspects of the design, procedure and results of these eight studies are summarized in Tables 1 and 2. Therefore, naturalistic alcohol consumption studies and laboratory studies that did literature review alcohol research employ a placebo can be considered as being suggestive of hangover effects, but should not be interpreted as providing definitive evidence of such effects.

Several pathophysiological changes that both follow and outlast acute intoxication may give rise to alcohol hangover effects.

In addition several supposed hangover studies report carrying out performance testing at elevated BALs.

Epub Jul They reviewed several studies claiming to show performance effects of hangover, but they recounted findings without any critical evaluation, and they omitted a large number of published peer-reviewed hangover performance studies.

Although some of these efforts have been shown to be effective in reducing alcohol misuse in youth, hardly any intervention reveals satisfactory outcomes in a long-term prospect.
